Russia’s fallen finance minister was tossed out of his office on Tuesday and told that he would have to leave his government country house in what appeared to be swift retribution for defying President Dmitri A. Medvedev that was clearly meant as a warning to other would-be rebels. Few could have predicted such an ignominious end for the finance minister, Aleksei L. Kudrin, who was fired on Monday for publicly questioning Mr. Medvedev’s authority and was quickly replaced on Tuesday by his deputy, Anton G. Siluanov, on an interim basis. After nearly two decades of government service, Mr. Kudrin was widely considered to be indispensable to the government. But even as the Kremlin moved to quiet the tumult raised by Mr. Kudrin’s dismissal, few were certain that it could repair the cracks in the ruling elite that his confrontation with Mr. Medvedev exposed.
